I have an old table mic with a 5 wire cable that someone had hardwired into a small amp. I've repurposed the amp, and now I want to fix the mic, but I'm not having much luck finding a wiring diagram for a 3 pin XLR connector.

Anyone know how to properly connect these wires to a 3pin connector?

BSI-870L


I've found this:

Can I just double up the appropriate wires to make a single connection? Looks like I'd combine red with white and yellow with black?

    You're not going to get an answer to this. You need to disassemble the mic and determine the internal connections for each of those wires - otherwise it will be impossible to work out which wires are for what. Also consider that the mic has a switch. Once you know the internal wiring then you will be able to work out the pinout for the XLR. Get thee to a screwdriver. – Mark May 15 at 2:30

    My guess is that oner or two of the wires connect to the switch that was used to control something outside the mic. That would leave one wire + ground or perhaps more for the mic. It is difficult to know though. The mic might want to be powered somehow, or it might be a dynamic mic not requiring any power. I would try by connecting any two wires to pin 2 and 3 of the XLR and then test it. If not working, change to a different kombination of wires until it works. Good luck. – ghellquist May 18 at 20:45
